Maybe @ HKG.
Looking at the loadings, Qantas are taking no more J or W bookings.
In June we flew LHR-SIN an an aircraft that had Y+ originally, but was subbed at 2 days notice with a 3 class. AFAIK, all Y+ bookings were accommodated in J.
Here Qantas have a 1½ weeks to attend to this; Perhaps they are hoping some PAX move flights.
